Kobi Lawn Robot
Autonomous lawnmowers have been around for a few years now. But the Kobi Lawn Robot is far more than just a high-tech grass-cutter. In the summer, it can keep your lawn mowed, using weather forecasts to know when to cut and mulching the clippings to keep your yard healthy. In the fall, a separate module lets it clear both your yard and driveway of leaves, and during the winter, the snow module dutifully clears your driveway so you don't have to venture out in the cold — unless you want to, of course. It's powered by quiet, efficient brushless motors and a lithium-ion battery, and will automatically return to its charging station when it's running low on juice.
